Title: Method of, and apparatus for, regulating co-acting water power stations
IPC: H02J3/46
Filed: 1948-08-26
Abstract: 671,659. Centrifugal governors. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 26, 1948 [Aug. 30, 1947], No. 22484/48. Class 57 [Also in Group XXXV] In an A.C. power network comprising a group of parallelly connected water-turbine power stations, some of which are regulated to maintain the network frequency constant, while the others are normally regulated according to a constant mean water consumption programme, at least one of the latter stations is provided with a regulator auxiliary to the main regulator whereby the station assists in frequency regulation without affecting the mean water consumption. This is accomplished by utilizing the temporary change of energy which occurs in the station as a result of operation of the main regulators when the load and therefore the frequency on the network varies and restoring the main regulator to its normal mean consumption condition under the control of its auxiliary in accordance with the experimental load. It is stated that restoration according to this load ensures that over a period the preset mean water consumption is maintained. An auxiliary regulator to a main regulator is shown in Fig. 1, and comprises a potentiometer 5 preset to the desired mean water consumption, and a potentiometer 6 operated by the water valve of the turbine, the potentiometers being interconnected by a motor 1 which controls the spring-setting mechanism of the main governor. Upon a change of load on the power network the potentiometer 6 is displaced by reason of the operation of the governor and the motor 1 is thereby operated to effect restoration of the governor and thereby the potentiometer into correspondence with the potentiometer 5 according to the expotential load. In modifications, Figs. 2 and 3 (not shown), the motor 1 may co-operate with an electric main regulator instead of a mechanical governor type or the motor 1 may be replaced by a pair of motors which through the intermediary of a differential gear and further potentiometer control the governor setting spring.

Title: Improvements relating to dampers
Inventor: PURPLE LESLIE PERCY
IPC: F23L13/00
Filed: 1958-07-14
Abstract: 922,589. Dampers. BABCOCK & WILCOX Ltd. July 14, 1959 [July 14, 1958], No. 22539/58. Class 51 (1). A damper having a pivotally mounted blade connected by a coupling to operating means by which the blade may be rotated to any position within a specified range, the coupling including resilient means and being such that play may occur between the operating means and the blade against the action of the resilient means which at any position of the blade in the range tends to prevent play. The blades 2, Fig. 1, of a furnace damper are pivoted within an opening 1 by a common operating bar 18 on which pins 19 are mounted for co-operating with doublearmed levers 8, 9. Each arm 8 is rigidly connected to the spindle 7 of a blade and the complementary arm 9 is freely rotatable about the spindle without significant play. Axially separated rollers 20, 20a, Fig. 5, are rotatably mounted on each pin, the arms 8, 9 being urged by a spring 17 into contact with the rollers 20, 20a respectively. The bar is reciprocated along the direction of its length by rotation of a crankshaft 21 and link 23. In the open position the arms 8, 9 firmly clamp their respective rollers on the pins so that the blades are fimly located relative to the bar and in the closed position anti-clockwise rotation of the crank-shaft moves the bar and so rotates the levers which positively grip their respective rollers under the action of the springs until each blade 2 engages projections 5a within the opening. Further rotation of each blade is impossible but each lever 9 is freely rotatable on the spindle so that further movement of the bar rotates the lever which compresses the spring and biases the blade towards the closed position to ensure a firm closure by the blale. Specification 873,524 is referred to.

Title: Improvements in or relating to vulcanizers
IPC: B29D30/06
Filed: 1939-08-03
Abstract: 531,846. Vulcanizing rubber. FIRESTONE TYRE & RUBBER CO., Ltd. Aug. 3, 1939. No. 22546. Convention date, Aug. 17, 1938. [Class 87 (ii)] The cover of a vulcanizer of the watch-case type is locked in the closed position by a ring which can be operated only when the cover is in the closed position. The cover 11 is raised and lowered by a piston 35 operated by fluid pressure through a reversing valve 41, and is held in raised position by a rod 48 pivoted at 49 and engaging a notched plate 50 on the frame. Manual displacement to the left of a rod 44 frees the rod 48 and reverses the valve 41 so that the cover descends. As the cover closes it depresses a plunger 68 which closes a switch 67 and starts the motor drive of a timer. The timer operates a valve to allow air pressure to a cylinder 17 which rotates the locking ring 13 to locked position, and the ring 13 then operates a valve to allow steam into the expansible core in the tyre within the vulcanizer. When sufficient time for the vulcanization has elapsed, the steam is cut off, the air pressure to the cylinder 17 is reversed to cause the locking ring to be withdrawn and finally the piston 35 is operated to raise the cover. The cover is pivoted at 32 to arms 31 on the frame so that it begins to rise without altering its horizontal position, but afterwards reaches the position shown owing to the engagement of a lug 58 with a lip 63.

Title: Improvements in or relating to processes for the production of metals and their alloys
IPC: C22B60/02
Filed: 1957-07-23
Abstract: Metals having atomic numbers greater than 89, e.g. thorium, uranium, protoactinium and plutonium are produced by reduction of their water-free and oxygen-free halogen compounds with reducing metals, such as alkali metals and alkaline earth metals, in the presence of an auxiliary metal selected from mercury, zinc or cadmium at temperatures above 360 DEG C., under superatmospheric pressure.  The produced metal combines with the liquid auxiliary metal, the halide of reducing metal floating in liquid state on the molten metal product.  Additives may be introduced to ensure that the by-product salt phase is produced in the liquid state, e.g. other halide salts which form with the salt product mixtures of low melting point.  The actinide metal may be alloyed with other metals such as aluminium, titanium or zirconium, the alloying metal being added to the reaction vessel with the auxiliary metal.  After separation of the salt by-product the actinide metal, or alloy thereof, in powder form may be recovered by distilling the auxiliary metal.  Any excess of reducing metal can be distilled in the same operation and recovered for re-use.
